Characterization of a constitutive type III nitric oxide synthase in human U937 monocytic cells: stimulation by soluble CD23

open access: yesImmunology, 1997
The soluble cleavage fragment of the low‐affinity immunoglobulin E (IgE) receptor/CD23 (sCD23 25 000 MW) and antibodies directed against their receptors on monocytes, CD11b and CD11c, stimulate the production of nitric oxide (NO) by these cells and we have suggested that the enzyme involved could be related to the endothelial constitutive type III ...

ACE-inhibition prevents postischemic coronary leukocyte adhesion and leukocyte-dependent reperfusion injury [PDF]

open access: yes, 1997
Objective: Polymorphonuclear leukocytes (PMN), retained in the microvascular bed, can contribute to postischemic myocardial reperfusion injury. Since a beneficial effect of ACE-inhibition on reperfusion injury has been reported, we investigated the ...

Emerging concepts about NAIP/NLRC4 inflammasomes

open access: yesFrontiers in Immunology, 2014
NAIP/NLRC4 inflammasome complexes are activated in response to proteins from virulent bacteria that reach the cell cytosol. Specific NAIP proteins bind to the agonists and then physically associate with NLRC4 to form an inflammasome complex able to ...

Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target [PDF]

open access: yes, 2018
Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years.

Microvascular alterations in hypertension and vascular aging [PDF]

open access: yes, 2017
Hypertension and aging are characterized by vascular remodelling and stiffness as well as endothelial dysfunction. Endothelial function declines with age, since aging is associated with senescence of the endothelium due to increased rate of apoptosis and

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

open access: yesFEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Nanodiamond Quantum Sensors for Probing Free Radical Biology

open access: yesAdvanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Characterization of phospho-(tyrosine)-mimetic calmodulin mutants.

open access: yesPLoS ONE, 2015
Calmodulin (CaM) phosphorylated at different serine/threonine and tyrosine residues is known to exert differential regulatory effects on a variety of CaM-binding enzymes as compared to non-phosphorylated CaM.

Characterisation of type I and type II nNOS-expressing interneurons in the barrel cortex of mouse

open access: yesFrontiers in Neural Circuits, 2012
In the neocortex, neuronal Nitric Oxide-Synthase (nNOS) is essentially expressed in two sets of GABAergic neurons: type I neurons displaying a high expression and type II neurons displaying a weaker expression.

Exercise, cognition and Alzheimer’s disease: More is not necessarily better [PDF]

open access: yes, 2005
Regional hypoperfusion, associated with a reduction in cerebral metabolism, is a hallmark of Alzheimer’s disease (AD) and contributes to cognitive decline. Cerebral perfusion and hence cognition can be enhanced by exercise.
